Connecting profile for interconnecting three sheet pile wall components and an arrangement of sheet pile wall components comprising such a connecting profile

Abstract

A connecting profile is disclosed for interconnecting three sheet-pile wall components. The connecting profile has a basic body from which three identical lock profiles project in predetermined coupling directions. Each lock profile comprises a thumb strip with a central web on which is formed a thumb which extends transversely to the longitudinal direction of the central web. A curved finger strip points in the direction of the thumb strip and forms a lock inner chamber and defines a mouth opening for the lock of the sheet-pile wall component that is to be hooked in. The mouth opening and the lock inner chamber are designed in such a way that the lock of the sheet-pile wall component that is to be hooked into the lock profile can be pivoted in the lock profile by a pivot angle of at least 15 degrees.

1. A connecting profile having a uniform cross section for interconnecting three sheet pile wall components, comprising:
 a base body, from which three substantially identical lock profiles project in predetermined directions for hooking sheet pile wall components, wherein each lock profile exhibits a thumb strip with a central web on which is molded a thumb; said thumb strip runs at right angles to the longitudinal direction of said central web and projects beyond the central web; wherein said curved finger strip points with its free end in the direction of the thumb strip and forms with the thumb strip a lock inner chamber; said lock inner chamber is at least approximately elliptical or oval in cross section, and said lock inner chamber defines with the ends of the thumbs pointing in the direction of the finger strip a mouth opening for the lock of the sheet pile wall component that is to be hooked in; 
 wherein at least one of the lock profiles is tilted, as viewed in the cross section, in relation to its predetermined coupling direction; and 
 wherein the lock profile is tilted in such a manner that the lock of the sheet pile wall component that is to be hooked into the lock profile can be swiveled with its main direction of the application of force in a swivel range of at least ±8 degrees to ±12 degrees about the predetermined coupling direction.
